NCLEX RN Predictor Exam

1. In the Gram Stain procedure, which component acts as the mordant?

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. During a class on religion and spirituality, the nurse is asked to define spirituality. Which statement by the nurse best describes spirituality?

Correct answer: D

Rationale: Spirituality is a broad term that focuses on a connection with something greater than oneself and a belief in transcendence. It is a personal journey that arises from unique life experiences and the individual's quest to find purpose and meaning in life. The correct answer emphasizes the essence of spirituality, which involves seeking a connection with a higher power and believing in transcendence. Choices A, B, and C, on the other hand, define aspects of religion rather than spirituality. Choice A refers to a personal search for a supreme being, which is more aligned with religious beliefs. Choice B describes an organized system of beliefs about the universe, typically associated with religion. Choice C pertains to beliefs about existence after death, such as reincarnation or the afterlife, which are often religious concepts. Therefore, the best description of spirituality is focusing on a connection with something beyond oneself and a belief in transcendence.

3. When would chest thrusts be performed in an emergency situation?

Correct answer: C

Rationale: In the scenario of an emergency where a pregnant woman is choking, chest thrusts are performed to clear the airway obstruction. This technique is used instead of abdominal thrusts to avoid potential harm to the fetus. While chest thrusts are not as effective as abdominal thrusts in clearing obstructions, they are the preferred method in this specific situation. Choices A and B are incorrect as chest thrusts are not typically performed during CPR to initiate cardiovascular circulation or when assessing responsiveness of an unconscious patient. Choice D is incorrect as chest thrusts are indeed warranted when assisting a pregnant woman who is choking.

4. Nursing care plans are _______________?

Correct answer: B

Rationale: Nursing care plans are comprehensive documents created by registered nurses to outline individualized care for patients. These plans serve as guidelines for all members of the nursing team, including nursing assistants, to ensure consistent and quality care. Choice A is incorrect as CNAs typically assist in implementing the care plan rather than creating it. Choice C is incorrect as nursing care plans are utilized by all members of the nursing team, not exclusive to only nurses. Choice D is incorrect as nursing assistants also utilize nursing care plans to provide patient care effectively.

5. A physician has ordered that a client must be placed in a high Fowler's position. How does the nurse position this client?

Correct answer: D

Rationale: A high Fowler's position is a modification of the semi-Fowler's position, in which the client is seated with arms resting at the sides or in the lap. The high Fowler's position requires that the client's head and upper chest are elevated, and the backrest is at a 90-degree angle. This position supports breathing and appropriate chest wall movement, making it easier for the client to breathe. Choices A, B, and C are incorrect because a high Fowler's position involves the client being in a sitting position with the backrest at a 90-degree angle, not being face-down, lying with the head lower than the feet, or lying on the back with knees drawn up towards the chest.
